How much CPU is used by the Performance Analysis Stealth Collector?
There is one collector per instance, and the threshold for CPU consumption per collector is 3%. Per each collector on the host, run top, see how much CPU is consumed for the quest_sc_collector process, and divide each CPU consumption per collector by the number of CPUs.
For example, if you have 2 collectors on one machine (meaning there are 2 instances that are monitored) and top shows 10% of CPU consumption per collector A and 34% of CPU consumption per collector B:
10%/20CPUs=0.5% CPU consumption per collector A
34%/20CPUs=1.7% CPU consumption per collector B
Total of CPU consumption by the Collectors from the entire system: 0.5% + 1.7% = 2.2%.
Another example:
Let’s say that each collector consumes as much as CPU as it allowed (threshold of 3%), then the two collectors will consume total of 6% CPU from the entire system.
